To access the cockpit display test modes, do the procedures that follow:
NOTES:
1. Fault detection with diagnostics can only be done on the ground. The pilot has
the option to do a pass/fail test while airborne if this feature is not inhibited.
2. This procedure is valid when used with either a single or dual control panel.
(1) Make sure the aircraft configuration indicates Aircraft On Ground and Gear Extended.
(2) Set the Mode Select switch on the ATC/TCAS control panel to STBY.
(3) Push and hold the TCAS TEST button for a minimum of 9 seconds.
(4) Set the transponder 4096 Ident Code Number to any code except 0000 thru 0007,
0011, 0012, 0013.
NOTE: Do not use codes 7500, 7600, or 7700; these code are reserved for
emergency operation.
(5) Make sure the TCAS TEST MENU is being displayed on the TCAS display. It should
match the screen shown in Figure 6−1.
(6) Set the transponder 4096 Ident Code Number to 0000.
(7) If the system passes, a maintenance page similar to that shown on Figure 6−2 is
displayed. A failure results in a referral to one or more specific ident codes. Set the
indicated code on the ATC/TCAS Control Panel and follow the instructions given.
(8) If the system passes, set the mode switch on the ATC/TCAS Control Panel to MODE
S ON. This allows you to exit the expanded test mode. If a failure is indicated, set
the transponder 4096 Ident Code to the codes indicated by the automatic referral
system. The remaining screens shown on Figure 2−4 thru Figure 2−14 are examples
of the other maintenance pages.
